I just got word that I can pickup two G3 BW towers and a G4 tower tomorrow from a local Freecycle post. I'm told the two G3s may run and the G4 at least needs a new hard drive. They were posted as parts only so I'm hoping they can be made to work. Counting the iMac I just picked up this will be four Macs in less than a week which is a record for me.
